Abstract: Sarah Croke - is a postdoctoral researcher at Perimeter Institute. From Ireland and the UK originally, she received a BSc in Physics and Applied Mathematics from University College Cork, Ireland in 2003. After a brief stint as a radio astronomer, completing an MSc in Astrophysics, she studied Quantum Information and Quantum Optics under the supervision of Prof Stephen Barnett at the University of Strathclyde, UK, receiving a PhD in 2007. She has been a postdoc at PI since November 2007. She works in quantum information theory, and is interested in both theoretical and experimental aspects. Roger Colbeck - I completed my PhD in theoretical physics at the University of Cambridge in 2006, and was for one year a junior research fellow at Homerton College, Cambridge before moving to ETH Zurich in 2007. Having been a postdoctoral researcher there for two and a half years, I moved to Perimeter Institute, where I have been since. I do research in quantum information theory and quantum foundations.
